Monteiro's Swallow was common and generally high- 

 flying. It was readily distinguishable on the wing from the 

 last-named species by the larger size and by the greater 

 amount of white under the v/ing. 



Two of these birds have very little trace of white on the 

 tail-feathers. This bird is undoubtedly a southern and 

 eastern form of H. senegnlensis, but they appear to occur 

 together in certain parts of their range.
